  2. Endothermic gas - Wikipedia

    en.wikipedia.org/wiki/Endothermic_gas

    An endothermic gas generator could be used to supply heat to form an endothermic reaction. [ 1 ] Synthesised in the catalytic retort(s) of endothermic generators, the gas in the endothermic atmosphere is combined with an additive gas including natural gas , propane (C 3 H 8 ) or air and is then used to improve the surface chemistry work ...

  3. Endothermic process - Wikipedia

    en.wikipedia.org/wiki/Endothermic_process

    [5] The opposite of an endothermic process is an exothermic process, one that releases or "gives out" energy, usually in the form of heat and sometimes as electrical energy. [1] Thus, endo in endothermic refers to energy or heat going in, and exo in exothermic refers to energy or heat going out. In each term (endothermic and exothermic) the ...

  4. Enthalpy change of solution - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_change_of_solution

    Dissolution can be viewed as occurring in three steps: Breaking solute–solute attractions (endothermic), for instance, lattice energy ⁠ ⁠ in salts.Breaking solvent–solvent attractions (endothermic), for instance, that of hydrogen bonding.

  5. Starch gelatinization - Wikipedia

    en.wikipedia.org/wiki/Starch_gelatinization

    As water is heated with starch granules, gelatinization occurs, involving an endothermic reaction. [8] The initiation of gelatinization is called the T-onset. T-peak is the position where the endothermic reaction occurs at the maximum. T-conclusion is when all the starch granules are fully gelatinized and the curve remains stable.

  6. Thermal decomposition - Wikipedia

    en.wikipedia.org/wiki/Thermal_decomposition

    main definition: Thermal decomposition is the breakdown of a compound into two or more different substances using heat, and it is an endothermic reaction Examples [ edit ]

  7. Enthalpy of mixing - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_of_mixing

    In thermodynamics, the enthalpy of mixing (also heat of mixing and excess enthalpy) is the enthalpy liberated or absorbed from a substance upon mixing. [1] When a substance or compound is combined with any other substance or compound, the enthalpy of mixing is the consequence of the new interactions between the two substances or compounds. [1]

  8. Barking dog reaction - Wikipedia

    en.wikipedia.org/wiki/Barking_dog_reaction

    The "Barking Dog" is an exothermic chemical reaction that results from the ignition of a mixture of carbon disulfide and nitrous oxide. [1] When ignited in a cylindrical tube, the reaction produces a bright flash and a loud " woof " - reminiscent of a barking dog.

  9. Van 't Hoff equation - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_equation

    where ln denotes the natural logarithm, is the thermodynamic equilibrium constant, and R is the ideal gas constant.This equation is exact at any one temperature and all pressures, derived from the requirement that the Gibbs free energy of reaction be stationary in a state of chemical equilibrium.
